I used Talley Steel bases on mine, with Tallley QD vertically split rings (screw lock option, not the levers). The bases are kind of high and the sights are visible over them, but just barely. I wanted the option of using the sights.
If you go with Talley steel bases, the thick lug on the base goes forward. I turned these bases around before I locktited them down.
Important: It's an aluminum receiver with steel thread inserts. The manual doesn't have scope base torque specs so I called Browning and was told NO MORE than 18 inch pounds. The man I spoke with told me he uses 15 inch lbs and blue locktite. I did the same thing - 15 inch lbs. After 50 or so rounds through the .308 and 100 or so through the .358, they are holding perfectly.
